I recently installed ubuntu 12.04 LTS on my acer c700 chromebook. I am unable to figure out if the SD card won't mount or if it's a driver issue.

Here is the test I have done so far looking up other people's problem:

Looks like the computer see the hardware,

02:00.1 SD Host controller [0805]: Broadcom Corporation NetXtreme BCM57765 Memory Card Reader [14e4:16bc] (rev 10) (prog-if 01)

Checking if it sees the Sd card with 5 sec apart between checking it

Seems it doesn't see anything. What's my next step? I have read something about gparted or gdisk. Is that the next step i should do? I don't even know which one is the slot.

Also running a command (i forgot) that checks the disks only see my 16gb hard drive.

EDIT more info

My Guess when the card is in there boots up, it's giving me this error message. Then, looks like it can't read the partition table?

EDIT#2 Well after few more hours tinkering, I have more answers with no solution.

  1. It will NOT see a micro SD card in anyway I play with it. Except with the log above, it sees it then turn off the reader it seems. It saw the size of the card as 29.4Gib, but unable to get the system to see/mount or use it.

  2. The computer will only mount the card in 2 ways; first one is boot ubuntu with the card already in the slot; OR insert card while system is running THEN plug in any flash drive, it will then mount the card.

  3. When the computer sees the card, the device is mmcblk0; but with the card inserted before booting, the device is mmcblk0p1. With that, not sure what I should dedicate the script to.

  4. Gpart won't see/detect the card or device (mmcblk0 or mmcblk0p1) at all if any of the above is unable to see the card.

Right now the only thing that works is to boot the system with a non-micro SD card in the slot. then it will see the card and read/write.
